Series 505 P/C, starting at memory location 100 (hex =

64).

The format for the request

follows:

Request: LLLL 20 TT NNNN AAAA = 0006 20 01 0004 0064, where:

LLLL (Length) = 0006

Primitive Code = 20

TT (Data T

ype) = 01 (V

, variable memory)

NNNN (Number of locations) = 0004

AAAA (Address, data element location) = 0064

Response: LLLL 20 HH DD ... DD = 000A 20 00 8464 8665 A001 01F4

LLLL (Length) = 000A

Primitive Code = 20

HH (Status) = 00 (unit operational and executing logic)

DDDD ... (values read from V memory)

V0100 = 8464



V0101

= 8665
